partition table incorrect/ fdisk messed up?
Hi everyone,
in the course of fixing another problem (thanks for the help everyone)
I discovered something odd on my system.
My (currently oly) hard drive is an 80-gig maxtor. here's the
partition table:
--------------------
sudo fdisk /dev/hda
The number of cylinders for this disk is set to 9732.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/hda: 255 heads, 63 sectors, 9732 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 373 2996091 83 Linux
/dev/hda2 374 871 4000185 83 Linux

/dev/hda10 3901 5116 9767488+ 83 Linux

and here's the output of df -h
matt@anarres:~$ df -h

/dev/hda10 9.2G 5.8G 2.9G 67% /home
-------------------------------------
as I read these two tables, I should have just under half the disk
free, amounting to almost 40 gig. And yet when I try to add a
partition in fdisk ('n'), it tells me "No free sectors available".
What am I missing?
one last bit of information: in "expert" mode (obviously I don't
quali\fy!), fdisk prints the following alist of extended partitions:
Expert command (m for help): e

10 00 0 0 0 0 0 0 0 0 00
does anyone know why hda10 (/home!) has only 0's in its listing?
thanks as usual!!!,
matt
